The Ford F-650/F-750 Super Duty are medium-duty commercial trucks produced by Ford since 2000. Prior to 2014, the trucks were produced in a joint venture between Ford and Navistar International. The replacement for the 1980-1998 F-600, F-700, and F-800, the F-650 and F-650 Super Duty are Class 6-7 medium-duty trucks, competing against the Freightliner Business Class M2 and the International Durastar. In 2011, upgrades to heavy-duty versions of the F-750 expanded the GVWR range into the Class 8 range, giving Ford its first truck in that range since the discontinuation of the L-Series in 1998.
